ARM: davinci: remove include/mach/ subdirectory

The files in include/mach are only used from mach/davinci,
so they are no longer needed in the traditional location.

Move them to arch/arm/mach-davinci/ and drop the logic for
the special include path.

The mach/uncompress.h file is not used at all and can just
be removed.
